' ADJUSTABLE SWITCH-POINT RAIL-SECTION.

To all whom it may concern:

Be it known that I, PHILIP CAMELI, a citi- Zen of the United States of America, residing at WVilmington, in the county of New Castle and State of Delaware, have invented certain new and useful Improvements in Adjustable Switch-Point Rail-Sections, of which the following is a specification.

The primary object of the present invention resides in the provision of devices associated with switch point rail sections to cause the free ends of the sections to lie in intimate engagement with the supporting ties at all times whereby the wheels ofrolling stock in passing over the point will not cause a vibratory movement thereof, in view of the rigid mounting of the free ends of the switch point rail sections.

A further object of the invention is to construct the tie bar of the switch point rail sections, known in the art as tie bar No. 1, with'the switch points carried thereby with the tie-bar being capable of adjustment relative to the supporting ties and adjacent rails so that the switch points may be adjusted to substantially frictionally engage the ties over which the switch points move so that the upper tread portions of the switch points will lie flush with the tread surfaces of the main rails.

IVith the above and other objects in View, the invention consists in the novel form, combination and arrangement of parts herein fully described and shown in the accompanying drawings, wherein like reference characters indicate similar parts throughout the several views.

Specification of Letters Patent.

Patented June 22, 1920.

Application filed November 22, 1919. Serial No. 339.797.

In the art to which this invention pertains, switch point rail sections after continuous use develop loose connections at their hinged ends or heels which permit a vibratory free movement of the opposite ends of the switch points and in the ordinary switch point at present in use and maintained in perfect working order, there is at least one-eighth inch loose play at the points and this degree of movement of the switch point increases to a swinging movement of three-fourths of an inch or more.

The wheels of the rolling stock in passing over the switch points if approaching at the heel end, cause the points to swing upwardly and when the wheels approach the free end bar which extend beneath the opposite end main rails is of extensible construction, screw devices causing a separation of the extensible ends of the tie bar, one section of the extensible end engaging the bottom face of the main rail base with the other section of the extensible end being moved downwardly therefrom which in turn lowers the central connecting portion of the tie bar and with saidconnecting portion the switch points. With this operation, the free ends of the switch points are moved downwardly into positive engagement with the supporting ties so that vertical movement of the free end of the switch point relative to the tie will be prevented with the result that the upper face of the switch point will lie flush with the rolls of the-main rail.

Referring more in detail to the accompanying drawings, there is illustrated a tie 6 of any preferred construction supporting the bases of the rails 7 secured thereon in any preferred manner as by headed spikes 8 engaging base flanges 9 thereof. A pair of switch point rail sections 10 are connected by the usual form of tie bars 11 spaced from the free ends thereof and known in the art as tie bars No. 2 while the improved form of tie bar 12, known as tie bar No. 1 conmeets the free ends of the switch point rails.

Tie bar No. 1 is shown more clearly in Figs. 2 to 5 and includes a central portion 13 extending between the rails 7 and adj acent the tie 6 with the opposite ends thereof downwardly offset to provide parallel extensions 14- underlying the bases 9 of the rails. A plate 15 is arranged between the rail base 9 and the offset portion 14 of the tie bar and carries adjacent each end thereof a downwardly directed pin 16 extending through an opening 17 provided in the tie bar offset 14 as clearly shown in Figs. 2 and 5 whereby the relative movement of the tie bar ends 14 and the plates 15 will be guided.

The switch point rail sections 10 are of any ordinary construction and are secured to the tie bar section 13 inwardly of the rails 7 by angle members 18 having bolts 19 passing therethrough and through the switch points and tie bars.

The tie bar 12 is in reality carried by the switch points 10 which in turn are sup ported on the ties 6 so that an adjustment of the sectional ends of the ties bars to cause a separation thereof will result in the lowering of the switch points 10 upon the ties for frictional contact therewith. The adjustment referred to is accomplished by a pair of screws 20 passing through threaded openings in the offset extensions 14% of the tie bar with the upper ends thereof having a free thrust bearing with. sockets formed in the bottom face of the plate 15 as shown in Figs. 2 and 4t. the central connecting portion 13 of the tie bar being maintained in adjusted position by the set nuts 21 upon the screw bolts 20. The lateral shifting of the tie bar with the switch points carried thereby is accomplished by the connecting rod 22 extending to a point suitably spaced from the track for operation in any'preferred manner.

Should the connecting heels of the switch point rail sections become worn to cause a limited movement of the free ends of the switch points, this loose play may be taken upv by adjusting the screw bolts 20 to force the plate 15 into engagement with the bottom face of the rail base 9 with the subsequent lowering ofthe offset portions 14: of the connecting portions 13 of the tie bar 12 and with said offsets 14, the connecting portion 13 and the switch points carried thereby thus hold the free ends of switch points substantially rigidly seated upon the ties to eliminate the free vibratory movement thereof caused by rolling stock passing thereover. Vith this device, a fine adjustment of the parts is possible, pressure being exerted upwardly upon the bottom face of the rail base 9 and exerted downwardly by the switch point rail sections 10 on the upper faces of the ties, the two forces working in opposite directions to prevent relative movement of the switch points 10 and the tie 6. This invention is to be viewed in its broadest aspect and while the preferred form of the device is illustrated, it is to be understood that many changes may be made therein such as the relative proportions of the different parts and substitutions of equivalents in so far as the operation thereof in the manner above described is obtainable.

What is claimed as new is 1. In combination, a pair of switch point rail sections, and a tie bar connecting the same, the tie bar being adjustable to cause the switch point rail sectionsto intimately contact the supporting ties.

2. In combination, a railway rail, a switch point rail section associated therewith, a tie bar carried by the switch point rail section and cooperating with the rail to cause the switch point rail section to frictionally engage the supporting tie.

3. In combination, a railway rail, a switch point rail scetion associated therewith, a tie bar carried by the switch point rail section and extending beneath the rail way rail, and means carried by the tie bar cooperating with the railway rail for causing a downward movement of the switch point rail section.

4:. In combination, a railway rail, a switch point rail section associated therewith, a tie bar carried by the switch point rail section, a plate carried by the tie bar and arranged between the tie bar and railway rail and means for causing a separation of the tie bar and plate supported thereon whereby the switch point rail sec tion is lowered onto the supporting tie.

5. In combination, a railway rail, a switch point rail section associated therewith, a tie bar carried by the switch point rail section, a plate carried by the tie bar and arranged between the tie bar and railway rail, the plate and tie bar having cooperating parts to guide the movements thereof and means for causing separation of the tie bar and plate supported thereon whereby the switch point rail section is lowered onto the supporting tie.

6. In combination, a railway rail, a switch point rail section associated therewith, a tie bar carried by the switch point rail section, a plate carried by the tie bar and arranged between the tie bar and railway rail, the plate and tie bar having cooperating parts to guide the movements thereof, and thrust screws extending through the tie bars beneath the rail for engagement with said plate to cause the plate to engage the base of the rail withthe subsequent lowering of the tie bar and switch point rail section onto the tie.

In testimony whereof I afiix my signature.

PHILIP CAMELI.
